Microscope Objective HC PL IRAPO 20x/0,75 W
$undefined
Whereas PL APO objectives are corrected in the visible wavelength range, with the PL IRAPO objectives a new set of specialized objectives is now available for improved multiphoton imaging (MP). The IR Apochromats are color corrected from at least 700 nm up to 1300 nm and highly transmissive in the visible and infrared wavelength ranges with > 85 % transmission from 470 – 1200 nm. Thus they are ideal for non-linear imaging like multicolor multiphoton imaging including excitation with OPO (optical parametric oscillator), and CARS (Coherent Anti-Stokes Raman Scattering).
